Why You Want It
Because the factory step rear filler is one of the first pieces to fail on these cars, and clean originals are nearly impossible to find. This Spoolfool fiberglass replacement gives you a durable, lightweight solution that’s ready to be prepped and painted to match your build. Perfect for street cars, show cars, or race-inspired setups where clean rear-end lines matter. Restores the rear bumper area while eliminating brittle factory plastic issues.

All parts are sold as-is with no returns, refunds, or exchanges. Buyer is responsible for verifying fitment for their specific application prior to purchase. Fiberglass parts may require trimming, sanding, and test fitting during installation. Turbo 6 Parts makes no performance guarantees. All sales are final.
